All of my other skids run hex heads except the very first batch. Not a single complaint yet. Countersinking 3/16" is not something I will consider. The strength would disappear with the head of the bolt. I would much rather fix a bolt than have to weld my skid plate because a bolt ripped through it.

so the pressure of a rock pushing up on the skid plate would cause the head of the bolt to rip thru the skid?
